The receivedBy field on a ChainOfCustody documents who at the laboratory took possession of your samples. This name appears on the lab's receipt confirmation and is often the person who logs the coolerTempC and receiptCondition. Capturing this information in Piper means you have a complete custody record: who collected, who shipped, and who received — the three handoffs that define chain-of-custody integrity for regulatory and legal review.
